The LBE Unlimited AR-15 Buffer Retaining Pin (brand part no. ARBRP) secures the buffer retainer and detent spring in the lower receiver, keeping the buffer assembly locked in place during every cycle. Sold as a 10-pack, it is an easy way for builders, gunsmiths, and armorers to keep spares on hand instead of ordering a single pin every time one goes missing during a build or teardown. Finished in black steel, it matches factory AR-15 hardware and installs the same way as the original equipment pin. It is a cheap insurance policy against a lost pin derailing a build or repair.
